#13000: minor doc bug about list fusion in GHC user's guide -------------------------------------+------------------------------------- Reporter: George | Owner: Type: bug | Status: new Priority: low | Milestone: Component: Documentation | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Documentation Unknown/Multiple | bug Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- First, the Users Guide (8.0.1.20161117) in section 10.32.6,List fusion, should mention length as a good consumer. Secondly, it says: "If you want to write your own good consumers or producers, look at the Prelude definitions of the above functions to see how to do so." However if you go to https://hackage.haskell.org/package/base-4.9.0.0/docs/Prelude.html and look at the source code for length you end up at https://hackage.haskell.org/package/base-4.9.0.0/docs/src/Data.Foldable.htm… which is not a good consumer. I think the User's Guide should be changed to replace "Prelude" with "https://hackage.haskell.org/package/base-4.9.0.0/docs/src/GHC.List.html". -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13000> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#11425: The GHC API doesn't provide a good hscTarget option for tooling -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: feature | Status: new request | Priority: high | Milestone: 8.2.1 Component: GHC API | Version: 7.10.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Other Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Tools like ghc-mod typically just want `TypecheckedModule`s. Sadly, the GHC API currently doesn't provide a good way to get at these in all cases (see this [https://github.com/DanielG/ghc-mod/issues/205|ghc-mod ticket]). Each of the options we offer are cursed with their own limitations (largely quoting from the ghc-mod ticket), == HscNothing == At first glance this looks like what you would want. But... * Pros * Doesn't generate code of any sort and is therefore rather lightweight * Cons * It lacks support for Template Haskell * Has trouble with `foreign export`s * [https://github.com/DanielG/ghc-mod/pull/145|Fails} to issue pattern match checker warnings == HscInterpreted == Okay, so `HscNothing` doesn't work. Maybe `HscInterpreted` is better? * Pros * Supports Template Haskell * Cons * Can't deal with unboxed tuples (#1257) * Slower as we need to produce unnecessary bytecode * Large memory footprint * Also can't deal with `foreign export`s == HscAsm == * Pros * Supports all compilable code * Cons * Slow * Produces `.o` files This is quite unfortunate. It seems like we need something in between `HscNothing` and `HscInterpreted` which is willing to use the interpreter to evaluate Template Haskell splices when necessary, but doesn't produce bytecode. Unfortunately it's unclear what to do about `foreign export` (but arguably most tools would be fine with some approximate representation). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11425> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
